Power quality is a critical challenge in grid efficiency and security, as well as more recently smart grid security, and it is anticipated to be strongly affected by electric vehicle (EV) growth in the future years. Because of their operating mechanism and the nature of their switching power semiconductor components, electric vehicle interface systems employ power electronic converters which are highly nonlinear systems. Consequently, substantial harmonics are frequently found in the converter's input current. This problem deteriorates the power quality in the power system, specifically harmonics and power factor. The most essential power quality factors are voltage sag/swell, current, active and reactive power, and harmonic voltage and current content. The energy levels should be between the limitations stated in the specifications to assess whether it has a sufficient power level. Power quality challenges created by EV charging as a separate form of electrical demand must be closely monitored.

Therefore, the primary issues throughout electric car charging are harmonics calculation and evaluation. According to the calculations, these high-power electronic loads generate substantial disruption on the source side. In order to determine the proposed control output, the voltage and current are monitored. The overall harmonic distortion value may be calculated using the harmonic disturbance graph. To solve these challenges, electric car charging efficiency must be increased.
